Abstract

L'invention porte sur un procédé de filtrage récursif de données discrètes de mesure de temps b¿ni? (50) relatives à un attribut mesurable variant dans le temps pour obtenir la grandeur estimée de l'attribut à un instant n donné. A chacune des mesures est associé un indicateur de fiabilité X¿ni? (52) représentant la fiabilité relative de la mesure. En utilisant les différents indicateurs de fiabilité, et l'indicateur de fiabilité filtré pondéré sur l'instant t Z¿n-1? pour l'instant précédant t, on obtient l'indicateur de fiabilité filtré z¿n? (58) pour l'instant présent. L'indicateur de fiabilité filtré pour l'instant présent permet alors de pondérer fiablement la moyenne pondérée (b¿n?) de la série de mesures et la grandeur estimée s¿n-1? à pondération temporelle pour l'instant précédant. Les valeurs pondérées sont alors utilisées pour créer la magnitude estimée s¿n? (68) de l'attribut variant dans le temps à l'instant présent.
